Transcribed Image Text:Drug Concentration
When a drug is injected into the bloodstream of a patient through
the right arm, the drug concentration in the bloodstream of the left
arm t hours after the injection is approximated by
C(t) =
at
t² + b'
for some values a and b.
Lab tests show that those values for Artecoadipine are a = 0.28
and b = 5.96, for 0 < t < 24.
The model suggests that after injection, the drug concentration of
Artecoadipine in the left arm is increasing until some time T hours,
and decreasing afterward.
Find T. Round to 2 decimal places.
